Question

the mixture of three gases is kept in a 25 l flask at 350c the molar fraction of he in the mixrture is 0.344, and that of n2 is 0.256. what is the partial pressure of co2, the hitrd component in the flask, if the total pressure 5 atm

Answer 1

The partial pressure of co2 is 2 atm by the concept CO2 partial pressure equals 0.4 x 5 = 2 atm.

mole fraction of CO2 * ptot = partial pressure of CO2.

CO2 mole fraction equals

1-(0.344 + 0.256) = 0.4

CO2 partial pressure equals

0.4 x 5 = 2 atm.
